Each port in the stack has a specific Unit ID, port type, and port number, which is part of both the
configuration commands and the configuration files. Configuration files are managed only from
the device Stacking Master. This includes:
•
Saving to the FLASH
•
Uploading configuration files to an external TFTP server
•
Downloading configuration files from an external TFTP server
Whenever a reboot occurs, topology discovery is performed, and the master learns all units in the
stack. Unit IDs are saved in the unit and are learned through topology discovery. If a unit attempts
to boot without a selected Master, the unit does not boot. For example, if a stack member (unit IDs
3 - 6) is separated from the stack due to a topology failure, the stacking member is no longer
connected to the stack. The device can be booted, but it cannot be managed through the Stacking
Master. The network manager can either reset the device defaults, or correct the topology failure,
and reconnect the unit to the stack.
Configuration files are changed only through explicit user configuration. Configuration files are
not automatically modified when:
•
Units are Added
•
Units are Removed
•
Units are reassigned Unit IDs
Each time the system reboots, the Startup Configuration file in the Master unit is used to configure
the stack. If a stack member is removed from the stack, and then replaced with a unit with the same
Unit ID, the stack member is configured with the original device configuration. Only ports that are
physically present are displayed in the GS700TS web pages, and can be configured through the
web management system. By default, Unit IDs are assigned automatically. However, you can use
the browser to assign a specific Unit ID; for example, the same unit ID as the unit which was
recently removed.
Inserting a Stacking Member
When a stacking member is inserted into a running stack, it is automatically assigned a unit
number. Note that a unit should not be powered up until it has been connected to the stack. If the
user has already configured a Unit ID for the newly joined unit, a new Unit ID is not assigned.
Note that all stack members must run the same version of firmware.
